The block 212 squeezes the connected spring 214, so that the drill pipe 211 is removed from the connecting sleeve 210. Put the new drill pipe 211 into the connecting sleeve 210, release the pull rod 213, and the acting force of the spring 214 drives the block 212 to slide out of the cavity. Rotate the drill pipe 211. When the block 212 is not squeezed, the block 212 slides into the card slot, so that the drill pipe 211 is installed inside the connecting sleeve 210.
